For when the garage is the kids' hangout... Maybe not all windows so the kid mess isn't visible to the world but some windows and definitely keeping the garage doors. Helpful when they move out and I can have my garage back. :-)

Garage door-style glass walls, great dark wood, black decor, and orange accents all throughout the house. I'm in love.
someday i shall have a garage door that opens to my awesome patio. via poppytalk
